DSD’s engineers use the industry-standard CAD systems, including CATIA, NX (formerly Unigraphics), Creo (Pro-E) and Inventor (Autodesk) and always uses the customers preferred system. As well as design, these tools are also used to provide integrated analysis and simulation packages.
DSD uses and is a beta tester of MASTA software for the simulation and engineering of transmissions and drivelines. This integrated driveline system design and analysis software, written by Smart Manufacturing Technology, incorporates: 2D design layout of a full transmission; gear design and analysis; 3D LTCA of gears with root stress; Bevel and Hypoid gear design and analysis; advanced bearing contact analysis; shaft fatigue analysis; NVH/dynamic analysis including full component mode simulation, and gear manufacturing simulation.
It is a versatile tool that enables an efficient creation of concept solutions. It provides detailed analysis on noise, durability or efficiency at an early stage, before investing in CAD time.
The DSD team uses FEA to evaluate individual components and full systems for stress, stiffness and fatigue. By using MASTA first we can highlight any issues that need to be evaluated through FEA and also accurately determine the deflections that need to be simulated.
Using FEA and MASTA we would commonly evaluate the following criteria:
Real-time plant model and non real-time high fidelity simulation models allows full understanding of complex interactions.
Extensive time domain detailed simulation capability:
